Patient Already Lost One Implant: What Treatment Plan is Best?

This patient sought help with us after losing one of her 5 implants, which were placed and restored about 2 1/2 years ago at some other practice. She also complains about a loose implant. Medically she is fit, however has a history of successfully treated carcinoma (not oral) 5 years and going. Clinically the maxillary bridge is mobile. This is a fixed bridge cemented on 4 abutments. Can’t see any buccal fenestration or pus. The restoration has a large cantilever on upper right side. I am planning to remove the bridge due to the overload and replace it with a cast bar + denture on 4 implant. My question is: Should I try to retain the implant and augment bone around them or explant all implants, grafting the sockets and go back in 6 months? Thanks.

locators?!!! the implants are only half a way in the bone!

well what do you suggest sir? They have peri-implantitis but are intergrated it will work. Just use light retentive elements. What else do you suggest ??? balls don't work as well. Bars will make hygiene difficult and will cost the pt more

Something for sure, I won't restore loose implants or ones with perimplantitis......

Awful prosthetic treatment, but I would not remove it until it stops working. Thorough hygiene will help elongate the implants’ use. After loosing them, a new evaluation of bone is necessary to give appropriate advice. In any case, a future denture must be extended according to antagonists from both sides.

You have a decent plan. If the implants are somewhat mobile, then flap, clean detox and graft with particulate of your choice. Start the bar procedure five months later. Use attachments of your choice.

I believe that bridge is mobile due to decementation on the right side? To just consider locators without bar you need to assess the angle b/w the implants. overdenture should ideally have maximum coverage, metal reinforced as teeth opposite.Preferably 10 teeth on denture if patient accept. For peri-implant bone loss will do peri-implant supportive therapy. wont explant yet as cantilever seems to be the main cause. remove over loading with effective periodontal care should do the trick

the dentist has taken an impression of the abutment in situ thats why it looks like it does on the right side. Like conventional crown and bridge.

Thank you for your replies so far. A question arises: in the case, if I would go with decontamination and augmentation, it would mean should not wear any denture for at least 3 months, which I couldn't ask for. What strategy would be more appropriate. I don't want to disturb the surgical site until complete healing was achieved. Thanks

sounds like you should refer out!

no i am making sense. I think with all due respect it sounds like your not confident in a solution for this patient. Its simple: -restore ailing implants with a locator with a full palate; locator abutments on minimum retention. Minimum retention to not overload implants and full palate if you loose one or all -at least she has soemthing to wear. -Take them all out!!-would you do that. They are the only options. Would you be happy completing this treatment on a family member confidently ?? if not refer out!! Plus by the sounds of your questions with all due respect they are not of an experienced implantologist. You shouldn't be doing this case, start small work yourself up with courses etc etc . It might sound firm but it will save you the hastle!!

@tomobooth thanks for your participation but you are not really talking sense. Please elaborate your thoughts or just leave it. thanks

i just think you don't like what i have suggested if you read my comments they similar to others maybe if you hadnt said locators?!!! the implants are only half a way in the bone i wouldnt have called you -yes they are in bone and integrated so restore palliatively as above!!! or refer out -that aint hard to understand!
drgil

it is nothing personal my friend and I never mentioned locators any where!!!! You still making no sense academically and try to put my qualifications, which you don't know anything about in question. Sorry I cannot take you seriously...

Academically : Dr T O Booth BDS Hons VuManc MSc OMFS PGDip (Implantiology) -where i come from that means you have teh qualifications to do implants and oral surgery!!!!! Sometime sthere is not an academic answer to everything. This a practical problem with a practical solution. Don't try and augment around these implanst it will not work. They look like Nobel replace select - which have a ti unite surface; which is WELL DOCUMNETED that is less favourbale for augmentation. Therefore if you were to augment yyou would grind the threads off first. THIRD LINE YOU MENTION LOCATORS!!!!!!!!!!!! Like i siad the best options are , -restore ailing implants with a locator with a full palate; locator abutments on minimum retention. Minimum retention to not overload implants and full palate if you loose one or all -at least she has soemthing to wear. Also distributes loads better. -Take them all out!!-would you do that?? Depends how old the patient is if young less than 50 then removal is possibly a better option. Then replace after soft then hard tissue augmention. Please don't make offensive comments when all i am trying to do is help you in this mess!!!!!!

Thank you for your help. Now I can understand what you meant, because finally you decided to elaborate your points!!! I will consider your advice for treatment planning this patient. I got to get the brand and type of the placed implant and remove the bridge first to check the path of insertion of those implants and their suitability for locators. Can you point me to the studies about ti unite surface? I think these implants the way they are now will last no longer than 3 more years with or without the overload. By then the boneloss would be much more significant.

You need to refer this out to a prostodontist, it is a lawsuit waiting to happen.

The implants are failing and it is a complex case

Great radiographs for a change, thanx for posting. I think your in a hole so stop digging. I would also refer to specialist, before he presents to the next dentist with your name on top of the failure list!

A good start would be to ask her to share the names of the previous treating dentists. Pts come to us often not wanting to share this, but you could learn a lot of helpful facts, and necessary facts before doing anything other than emergency work. As mentioned, if you take this on, you will be tossed into the garbage bin with all the other past treating dentists, but with a new "reset" of the statute of limitations. Besides, it's just the best thing to do - to know what has happened, how the patient has done with cooperation and home care, what areas were radiated, what her teeth and ridge looked like before. Beware of new, major cases who bad mouth the old dentist or refuse to divulge past treating dentists' names. If you try to overhaul these old, failing implants and bridge, you will inherit greater risk than the guy or gal who put them in without enjoying the remuneration of the original case. Get info, be kind, go slow, document problems, etc. John

Maybe you have room to place more and stronger implants between or behind these in order to reduce the load, and to isolate the past work from your newer work.

The case is FAILING probably due to prosthetic overload from the cantilever and against natural dentition the occlusal contact is also probaly contributing to the overload.All four iplants have threads supracrestal.There is no proven dependable way to "decontaminate the porous surface of the implants unless they are old machined surface fixtures.The patient needs to make the decision to salvage the case by converting to an overdenture using locators or a bar if the angulation does not lend itself to locators.The more ideal TP should be to remove the implants before more uncontrolled bone loss occurs graft and augmentation of the ridge and placing 4 fixtures for an overdenture,if the patient wants fixed prosthetics consider sinus lifts.This is a good example of trying to do to much with too little.

Personally, I would be inclined to salvage the existing implants and work toward sinus lifts and 2 to 4 more implants. I would section the bridge and if needed make a transitional RPD. Then do or have done sinus lifts, place implants and later restore the 4 new ones. Or, I might sacrifice the remaining upper bridgework and use only two new implants and make a new complete upper cementable fixed prosthesis.Good luck!

Pretty sure they are nobel bio-care replace select. Think they are a combo of narrow and regular platform but there may well be some wide platform in there aswell.
